BACKGROUND OF THE INVENTION

(1) Field of the Invention

The invention generally relates to refrigeration systems. More particularly, the invention relates to means and methods of producing a salad bar cooling system.

(2) Description of the Related Art

Other salad bar cooling systems are known in the related art. For example, U.S. Pat. No. 6,442,962 by Gaetke et al issued on Sep. 3, 2002 discloses an inflatable chamber to define a planar surface for holding food. While Gaetke does provide a portable solution, Gaetke's flexible surfaces and lack of integrated refrigeration makes Gaetke poorly suited for permanent salad bars, such as those found in restaurants.

U.S. Pat. No. 3,308,633 by Kritzer issued on Mar. 14, 1967 discloses a cabinet with a center heating and cooling motor. Kritzer fails to disclose means of artfully configuring cooling units to efficiently cool a salad bar.

Other refrigeration systems are known in the related art. For example U.S. Pat. No. 6,997,005 by Haasis issued on Feb. 14, 2006, discloses a refrigeration system with a sliding sub-unit comprising a centrifugal fan, fan motor, additional fan for cooling the fan motor, a flange and track slider assembly and a collection of springy metal stripes used to secure the sub-unit into a housing unit. Unfortunately, the system disclosed by Haasis leads to added noise and motor vibration due to the use of springy metal strips to secure the sub-unit to the housing. In order to achieve a secure and vibration resistant fit of the sub-unit, silicone or other materials are commonly used within the flange and track slider assembly. When a fan motor needs replacement, the typical service technician will not have the necessary sealants, which results in a newly installed motor causing unacceptable noise and vibration.

Another shortfall in the Haasis system is the inefficiency of using one motor to turn a single traditional centrifugal fan. Moreover, the overall design of the Hassis system requires the use of a second motor cooling fan to cool the motor also turning the centrifugal fan. The added load to the motor from the second cooling fan often creates more heat than what is removed by the second fan. Furthermore, the coil configuration of the Haasis system fails to adapt to varying food storage containers or other applications with untraditional dimensions and access problems. Moreover, the overall configuration of the Haasis system leads to a heavy cooling system making installation difficult in overhead locations.

BRIEF SUMMARY OF THE INVENTION

The present invention overcomes shortfalls in the related art by presenting an unobvious and unique combination and configuration of coils, blowers, a blower motor and other components to provide a compact unit with means of easily redirecting cooled air flow to fit various applications.

One of the main advantages of this invention is the creation of a twin cross flow blower system comprising two air blower turbines placed on either side of a unique cross flow motor. The twin blower turbines are sometimes referred to herein as a “cross flow blower” and are sometimes named “cross flow blower 1” and cross flow blower 2. The placement of a cross flow motor between the two disclosed cross flow blowers has achieved unexpectedly favorable results in efficiently moving cooled air to a targeted area.

The cross flow blowers feature a new and efficient air blade configuration as well as a highly moveable air flow diverter. The moveable air flow diverter allows the disclosed cross flow system to be adapted to many configurations to fit most applications.

The disclosed configuration of a center cross flow motor flanked by two cross flow blowers placed over a compact coil system provides clear advantages over the related art in terms of weight and size.

The disclosed coil systems also provide unexpectedly favorable results as they have been configured to adapt to untraditional locations.

Another advantage of the disclosed embodiments, including a second embodiment is a new fan and motor unit used with a new motor housing, the new motor housing allowing the new fan and motor unit to be easily installed in either a top discharge or side discharge configuration. In the related art, separate units were constructed to accommodate either a top discharge or side discharge application. Workers in the field would need to bring the correct machine for a particular job, or carrier two machines. Thus, the present invention, including the second embodiment presents a significant departure from the prior art.

The second embodiment overcomes shortfalls in the art by presenting a new fan and motor unit having artful fastening clips allowing the fan and motor unit to efficiently attached either of two positions within in the motor housing. The motor housing includes a back plate, fastener voids, two sets of discharge vents and other features not found in the prior art.

The present invention overcomes shortfalls in the art by use of the above described compact and convertible cooling units to create a new salad bar cooling system. A frame assemble artfully integrates with cooling units to efficiently remove heat from a food holding area. The disclosed frame assembly is sometimes called a salad bar frame assembly and overcomes shortfalls in the art by use of air circulation and air return systems that have achieved excellent results in real world commercial applications.

Embodiments of the disclosed salad bar cooler configurations use a top cooling configuration of a disclosed cooling unit in an artful combination with a disclosed salad bar frame assembly. The salad bar frame assembly is sometimes used with air diverter plates, supply air diffusers and outlets, pan chambers, various pan guards and other components. The disclosed air return assemblies work seamlessly with the native air return inlets of the disclosed cooler units. In the best mode known to date, a disclosed salad bar frame assembly is integrated with a disclosed compact and convertible cooling unit.

These and other objects and advantages will be made apparent when considering the following detailed specification when taken in conjunction with the drawings.

Accordingly, the actual scope of the invention encompasses the disclosed embodiments and all equivalent ways of practicing or implementing the invention under the claims.

Referring to FIG. 1 a typical food storage container 10 is shown with a front panel 18, side panel 14, a top panel 12 and voids or doors 20 used to access the interior. Variations of the illustrated food storage container may be found in supermarkets, restaurants and other places requiring the refrigeration of food.

Typically cooling units are placed within the back section of a food storage container introduce evaporator coils carrying a coolant in expanding gas form. As gas expands, the gas cools and absorb heat from the coils, the coils in turn absorb heat from the surrounding air. After absorbing heat, the gas within the coils travels outside of the food storage container. In this outside area, a compressor and condenser transform the gas into liquid form. An outside fan may be used to blow ambient air over the outside coils. On the return route to the food storage container, the liquid within the coil system passes through an expansion value wherein the liquid expands to gas, travels within the food storage container, cools and then transfers heat to the outside of the food storage container.

Coils containing gas and found within the food storage container are sometimes called evaporation coils 48 and are shown in FIG. 2 on the bottom of the disclosed system. The disclosed system sits within a food storage container or other application and accepts coolant that is compressed, allows the fluid to expand to gas within the evaporation coils and then outputs the gas to an exterior system as described above.

A key advantage of the disclosed system is the efficient movement of air over the evaporation coils and into the food storage area. Found at the top of FIG. 2 is a disclosed cross flow motor 300 which powers two cross flow blowers 100 and 150. The components of FIG. 2 are arranged such that they fit into a housing that may be approximately 4.5 inches deep, 21.5 inches across and 10 to 12 inches high. But, other dimensions and configurations are contemplated. In the preferred embodiment, all of the components of FIG. 2 are bolted or otherwise firmly attached to the housing.

The use of an extra fan to cool the motor as disclosed in the Haasis system is not needed in the system presented herein. Moreover, in order to achieve a compact size and sturdy construction, the disclosed system does not adopt the configuration of a sub-unit or the use of tracks to install components. Such a cumbersome system of attachment would detract from the compact and lightweight feature of the disclosed system.

Referring to FIG. 3 the general shapes and contemplated dimensions of the housing assembly 400 are shown. Alternative configurations for the housing assembly are contemplated and do not detract from the benefits of the disclosed system.

Referring to FIG. 4 a section view of one embodiment of a cross flow blower 100 is shown as well as an attached cross flow motor 300. FIG. 5 presents a plan view of the bottom side of a cross blower. FIG. 6 presents a side view of a cross flow blower and rotational plate 102 ready for attachment to a cross flow motor 300.

FIG. 7 presents a top perspective view of one embodiment of the disclosed invention. The cool air exit vents are covered in mesh and the entire housing assembly is supported by the fingertips of person of average strength.

FIG. 8 illustrates a more detailed view of FIG. 2 and shows a working model of one embodiment of the disclosed invention. FIG. 8 shows a void area at the bottom to allow entry of ambient air that passes through the condenser coils and into the cross flow blowers.

FIG. 9 presents a close up view of the cross flow motor 300 while attached to both cross flow blowers. The disclosed configuration places the cross flow motor 300 in close proximity to the evaporation coils, thus the extra motor cooling fan of the Haasis system is not needed. Also the surface area and shape of the disclosed cross flow motor provides ample motor cooling with excellent motor performance.

FIG. 10 presents two cool air output vents adjacent to the two cross flow blowers.

FIGS. 11 to 16 depict various parts and aspects of a first embodiment.

FIG. 17 depicts a second embodiment comprising a top plate 510, a condensation pan 500, a motor 515, a liquid line u bend 520, a TXV valve 525 one or more cross-flow blower wheels 530, a coated evaporator coil 535 and a sensing bulb 540.

The fan and motor unit also comprises a motor fitted in between the fan covers 583. The fan covers 583 cover a pair of cross-flow bower wheels.

FIG. 23 depicts a front discharge plate 545 in the foreground and a fan and motor unit in the background.

FIG. 24 depicts a plan view of a top plate of a motor housing.

FIG. 25 depicts a plan view of a back plate.

When a fan and motor unit is secured to a back plate 570, the fans will force cooled air out of the top discharge vents. When a fan and motor unit is secured to top plate 550 of the motor housing, the fans will force cooled air out of the side discharge vents.

The configuration of the fan and motor unit 575 having a plurality of fastening clips 575 compatible with fastening voids upon both the back plate and the top plate of the motor housing, allow the second embodiment to be converted in the field for either top or side discharge. The back plate 570 may be secured in a perpendicular position from the top plate 550 of the motor housing.
